Lead
The lead has been updated and my peer has added new content. A concise and clear introductory sentence was used to describe the article's topic and a brief description was also used to describe the article's major section. It was helpful that she described that the magma forms on the surface hence the "extruding part". She linked possible unknown terms such as "pyroclastics" which made reading easier, so you didn't have to separately look it up. The peer provided information outside the article in a well written way. She provided examples of extrusive rocks which was also very nice because some of these rocks are well known so it links common knowledge to a new topic. It was also great that she mentioned about extrusive rock forming quickly because it's on the surface and exposed to air.

Balanced Coverage
The content added pertained to her topic of Extrusive rocks. The information added was not out of place or awkward. It fit in well with the surrounding information

with the information around it. Everything was well described and provided a balance of information of the general what extrusive rocks were, why there is a lack of crystals and the formation of the rocks, and the components of magma and how it affects the rocks itself.
